A separation matrix impregnated with a separating agent separates red blood cells or hemoglobin from whole blood. Upon separation, an impregnated test reagent reacts with the separated substantially clear component fluid to form a colored product which enables a visual or meter test for analyte leve ...

A process for the manufacture of small sensors with reproducible surfaces, including electrochemical sensors. One process includes fanning channels in the surface of a substrate and disposing a conductive material in the channels to form an electrode. The conductive material can also be formed on th ...

Upon separation, an impregnated test reagent reacts with the separated substantially clear component fluid to form a colored product which enables a visual or meter test for glucose leve ...

A multilayer reagent test strip measures the concentration of analyte in a liquid sample that is applied to it. The sample is guided to a number of assay areas arrayed along the strip, where the analyte can react with a reagent to cause a color change. Each assay area also includes an inhibitor for ...

The present disclosure relates to a sensor including a bundle of electrically conductive fibers. The sensor also includes a sensing material coating at least some of the fibers in the bundle, and an insulating layer that surrounds the bundle of electrically conductive fibers.

A reagent strip for measuring glucose concentration in a biological fluid containing red blood cells has reduced interference of hematocrit with the glucose measurement. When a biological fluid contacts the strip, it causes, in a reagent impregnated in the strip, a color change which is a measure of ...

An in vivo electrochemical sensor including a working electrode, and an analyte-responsive sensing layer proximate the working electrode. The sensing layer is exposed at an edge of the sensor, wherein the sensor signal is limited, at least in part, by mass transport of analyte to the sensing layer. ...

A chemical timer for a direct-reading reagent test strip changes color a predetermined time after a biological fluid is applied to the strip. The strip measures the concentration of an analyte in the fluid. The timer is a dry coating of an indicator, an enzyme-containing reagent that when hydrated c ...

An analyte monitor includes a sensor, a sensor control unit, and a display unit. The sensor has, for example, a substrate, a recessed channel formed in the substrate, and conductive material disposed in the recessed channel to form a working electrode. The sensor control unit typically has a housing ...
